[MPlayer-users] Mencoder Audio Synchronization

Hi Everyone...
I am using an AthlonXp 2100+
with an Nvidia GeForce 4400
on a Slackware-current box

Movies that I download from other sites
and DVDs play fine on my machine
However whenever I encode my own DIVX movies my audio is always out of synch
with the video

Here is part of a small script that I wrote to encode videos:


rm -rf frameno.avi

# Encode Audio
/usr/bin/nice -n 19 mencoder dvd://1 -ovc frameno -o frameno.avi -oac mp3lame
-lameopts abr:br=160 -alang en

# Encode Video Pass 1
/usr/bin/nice -n 19 mencoder dvd://1 -oac copy -o /dev/null -ovc lavc -lavcopts
vcodec=mpeg4:vbitrate=1024:vhq:v4mv:trell:vpass=1:keyint=128 -ofps 23.976 -vf

# Encode Video Pass 2
/usr/bin/nice -n 19 mencoder dvd://1 -oac copy -o final_movie.avi -ovc lavc
-lavcopts vcodec=mpeg4:vbitrate=1024:vhq:v4mv:trell:vpass=2:keyint=128 -ofps
23.976 -vf pp=fd,crop=720:358:0:58


Can anyone tell me what is going on with this?  Can anyone tell me how to
improve the encoding process so that my audio comes out properly in my movies? 
Any help would be great...
